EUGENE JEN CI JOHN STEVENSON, OF JENKINS, KENTUCKY; SAID JENOI ASSIGNOR TO STEVE KRUCHIO, ROZLALIA TOWN, PENNSYLVANIA.

MARY SZABO, AND SARAH KRUGHIO, ALL OF UNION- RAI L-GONTACT FOR VEHICLES.

To all whom it may concern Be it known that we, EUGENE JENoI and JOHN STEVENSON, subjects of the King of Hungary, residing at Jenkins, in the county of Letcher and State of Kentucky, have invented certain new and useful Improvements in Rail-Contacts for Vehicles, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to rail contacts or current. collectors especially adapted for electric railways of the third-rail systenr type, where it is necessary to maintaln connection between electrical apparatus on a car, and a third rail.

The primary object of our invention is to provide a truck frame with a yieldable spring pressed contact for a rail that will compensate for any inequalities in the space between the truck frame and the rail, thereby insuring a positive contact and the usefulness of an electric circuit for operating purposes.

A further object of this invention is to provide a yieldable rail contact consisting of comparatively few parts that are simple in construction, durable and applicable to various types of electric vehicles.

With the above and other objects in View the invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed. a

Reference will now be had to the drawing, wherein 1 Figure 1 is a side elevation of a truck frame in accordance with this invention, Fig. 2 is a plan of the same, Fig. 3 is a cross sectional view of the truck frame, Fig. 4: is a longitudinal sectional view taken on the line IV-IV of Fig. 1.

Further describing our invention in detail with reference to the accompanying drawing, wherein like numerals denote corresponding parts throughout: 1 denotes a' truck frame having the ends thereof provided wlth plates 2 that permit of said frame being secured to bolsters or the body of a car (not shown). The frame 1 has a depending guide, comprising a vertical bearing 4 braced by angularly disposed or curved arms 5 The vert cal bearing 4 has a longitudinal doveta1led groove 6 and slidably mounted in th1s groove Specification Letters lPatent.

side of the bearing plate 7 is provided with two parallel hangers 8 and journaled in the lower ends of said hangers and the plate 7 are pins 9 upon whichthere are mounted contact wheels 10. The contact wheels 10 are adapted to engage a head 11 of a third rail 12 and the contact plate 7 extends down wardly at the inner side of the head 11 and serves somewhat as a guide for preventing the1 contact wheels from shifting off of the rai s.

The bearin plate 4. has the upper end thereof provided with'a horizontal extension 13 and interposed between said extension and the upper ends of the hangers 8 are coiled compression springs 14. The tension of these springsissuflicient to hold the bearing plate 7 in a lowered position, whereby the contact wheels 10 will engage the rail, yet permit of the contact wheels yielding when any irregularities are encountered in connec tion with the rail.

One embodiment of our invention has been illustrated, but it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims.

What we claim is 1. A contact for rails comprising a truck frame, a depending guide carried thereby, a bearing plate vertically movable in said guide, parallel hangers carried by the outer side of said bearing plate, contact wheels revoluble between said hangers and said bearing plate, and means engaging the upper ends of said hangers for holding said bearing plate and said hangers in a normally lowered position.

2. In a contact for rails, a truck frame, a

bearing plate slidably supported by said frame and extending down on the inner side of the rail, hangers carried by the outer side of said bearing plate, contact wheels revolubly mounted between said hangers and said bearing plate, and yielding means engaging the upper ends of said hangers for holding said hangers in a normally lowered position.

3. In a contact for rails, the combination with a truck frame and a rail, of a depending guide carried by said truck frame, a bearing said hangers and said plate, and coiled complate mpvable in said guide and extending @[ntestirnony whereof we aflix onr si gnadownward at the inner side ofLsaid .railf, .tures in thepresence oftwoiwitnesses; parallel hangers carried by the outer side 0 4 a said plate, revolnblepontact Wheels between V Witnesses STEVE.

pression springs engaging the upper ends of said hangers for holding said contact Wheels normally in engagement with said rail.
